Vertex of parabola y=ax^2 bx c
Vertex of parabola y=ax^2 bx c-Making b positive or negative only reflects the parabola across the yaxis So, the displacement of the vertex from the yaxis is caused by the absolute value of b Finally, let's look at how changing c affects the graph of the parabola We will look at the graph where c = 3, 2, 1, 0, 1, 2, and 3, a = 1, and b = 3 As we can see from the Show that y = ax 2 bx c, a ≠ 0 represents a parabola and find its vertex, focus, directrix and latus rectum

The standard form of a parabola equation is y=ax^ 2 bxc Input the values of a, b and c, our task is to find the coordinates of the vertex, focus and the equation of the directrix The vertex of a parabola is the coordinate from which it takes the sharpest turn whereas y=a is the straightline used to generate the curve So, the coordinates of the vertex are V = (x v , y v) = (5/2 , – 1/4) or (2,5 , 0,25) yaxis interception point The parabola intercepts the yaxis at the value of the c coefficient In the function above, the value of c = 6, therefore, the parabola intercepts the yaxis at the point (0, 6) Graph of a quadratic function As said before, the graph of a quadratic function is known as aThe graph of a quadratic equation in two variables (y = ax2 bx c) is called a parabola The following graphs are two typical parabolas their xintercepts are marked by red dots, their yintercepts are marked by a pink dot, and the vertex of each parabola is marked by a green dot We say that the first parabola opens upwards (is a U shape) and the second parabola opens

Please Subscribe here, thank you!!!F (x) = ax 2 bx c are given by the quadratic formula The roots of a function are the xintercepts By definition, the ycoordinate of points lying on the xaxis is zero Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax 2 bx c = 0 We can do this by completing the square as,We want to find the vertex of this parabola The vertex is on the axis of symmetry, so its $x$coordinate is 3 The vertex is also a point on the parabola, so it satisfies the equation for the parabola This means that if you plug the $x$coordinate of the vertex into the equation, you will get the $y$coordinate Plugging 3 for $x$ into $y=x^26x$ gives $y=(3)^26(3)$ → $y=918$
